Today a serious accident occured at the international show in Poznan. British show jumper Joseph Clayton's 9-year-old Belgian Warmbred Stallion, Gorre, wa euthanized after a fall in the tripple combination in the Grand Prix. The horse was diagnosed with a fractured leg. William Whitaker, who is Joseph's nephew, retired from the Grand Prix after the incident.   Since December 2014 the Toulon-son was in ownership of Valerie Whitfield and Mark Williams. Under the saddle of Clayton Gorre finished victoriously at the CSI3* in Lummen a couple of months ago. The pair also finished second and third in some 1.35 and 1.40m classes at the same show. Gorre got his first international experience with British rider Pippa Goddard. When they finished fourth in last years 1.35m in Dinard, it was Guy Williams who took over the horse. Our thought are with all the people that worked with Gorre
